Answer:
a=8
Step-by-step explanation:
We know that the right triangle has a total angle of 90.
We already have 50 witch means 40 is missing.
The equation given is:
6a-8 but we will upgrade it by the information we have so now it’s 6a-8=40
One of the multiples of 6 is, 6x8=48
Remember that 8 will be taken off.
Solve:
48-8=40 (witch is what we where looking for)
This is further proof that a=8
It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.
Choosing a group would provide the average height for that group, not the entire primary.
Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.
Explanation:
Since m is a unit in S, then, there exists b ∈ S such that m*b = 1, where 1 is the identity. Since S is a subring of R we have that m ∈ R, and therefore b is also the multiplicative inverse of m in R. The converse isnt true.
The set of real numbers is a Ring with the standard sum and multiplication. Every real number different from 0 has a multiplicative inverse. For example, the inverse of 2 is 1/2. However, 2 is not a unit on the subring of Integers Z.
A: minutes
16a > (with a line under it) 136
The awnser would be 8 minutes and 50 seconds. 136 ÷ 16 = 8.5
a > (with a line under it) 8.5
I hope I helped! :D
The answer is 6.35. Because you put in 254 / 40 and it says 6.35.
